Development of Vibration Base Health Monitoring in Bridge

Abstract

Abstract Vibration-based health monitoring uses non-destructive sensing technology to monitor and analyze changes in structural characteristics in time, frequency, or modal domains. The optimization of this system has always been the focus of the research community. Structural monitoring systems can start monitoring from building construction to destruction. It includes many kinds of methods and issues in different structure. This paper reviews the method of bridge structure damage identification based on vibration measurement that has been verified by the test. The use of the vibration excitation method is discussed, as well as the main issues currently. Structural monitoring systems determine that which and where damage is present in the structure, even the prediction of the remaining service life of the structure. In the field of civil engineering, structural monitoring systems have the potential to reduce economic losses and maintain modern infrastructure, even it may obvious geological changes to present disasters in the future.
